Abstract
The spin state of an electron has a 3-dimensional vector representation. In spin-orbit coupling (SOC), an electron’s external momentum becomes linked to its spin vector. This phenomenon appears in many different systems, including atomic and crystal band structure, (quantum) spin-Hall systems, and topological insulators. Previous experiments have used Raman coupling to generate and study several forms of SOC in pseudospin-1/2 ultracold gases. A similar method has been proposed to couple a quantum gas’ linear momentum with a spin tensor - a representation of a higher (spin-1+) state. While possessing a rich ground state phase diagram, this spin-tensor-momentum coupled system also provides an opportunity to directly observe a dynamical supersolid-like stripe phase with a tunable stripe period. This poster reports our experimental progress toward producing and characterizing this novel state of matter using a Rb-87 Bose-Einstein condensate.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
